Surface Coating of Miscellaneous Metal Parts

Summary of the Conference Call of Wire Coating Manufacturers and EPA PMACT Development Teams for Miscellaneous Metal Parts and Products and Metal Coil Surface Coating

May 16, 1997

The following summary presents the major issues associated with the surface coating of the miscellaneous metal parts and products and metal coil surface coating source categories as discussed in a conference call with the wire coating manufacturers. The issues listed below are presented in the order in which they were discussed, and no presumption of the importance of one issue over another was imposed.

Introduction to Wire Coating Manufacturers

Bob Schenker, of General Electric, and Carlos Cardounel, of Reynolds Metal Company, began the conference call with an overview of the types of products which utilize magnetic wire, such as; motors, generators, and transformers. Magnetic wire is not included in the Metal Coil surface coating category because there are many fundamental differences in the coating processes. The only similarity is that each category implements a continuous coating process rather than a batch. Mr. Cardounel described the typical coil coating line and how it differs from that of a wire or magnet wire coating process.

Questions/Comments/Issues - The following topics were addressed by participants during the meeting:

Participants questioned the inclusion of wire coating and magnetic wire coating in the
Miscellaneous Metal Part and Products category. There was discussion as to the process	of initial category determination under CAA 112(d). Participants asked about obtaining a	copy of the Magnet Wire CTG and the Miscellaneous Metal Parts CTG. These can be	acquired from George Woodall by request.

There was clarification of the process of wires coated by plastic extrusion. It was
determined that such coating would probably not be included in the Miscellaneous

Metal Parts and Products category.

Industry representatives would like to see magnet wire incorporated as its own
subcategory of Miscellaneous Metal Parts and Products. Magnet wire coating is unique	because of the solvent-based coatings that are used and the absence of plastic extrusion.

With regards to the PMACT process, participants were concerned that the PMACT would	include emission standards. EPA representatives responded that emissions standards	would not be set in the PMACT. Concern was also raised over the time frame allotted to	complete the PMACT.

EPA discussed plans for site visits to wire coating facilities. They are currently trying to
obtain more funding for travel. Possible site visits included the Phelps Dodge facility in	Laurinburg, NC which coats fine and medium gauge wire on horizontal lines, and the	General Electric facility near Atlanta, GA which has vertical coating lines.

NEMA representatives offered to provide a standardized schematic of the magnet wire
coating process.
